- Apparent molar volume and modeling of volumetric properties of ionic liquid aqueous solutions 1-butyl-3-metilmidazolium chloride [Bmim+][Cl-] at various temperatures Manuel Páez-Meza Omar Pérez-Sierra Yeris Cuello-Delgado Ingeniería density ionic liquid Pitzer parameters apparent molar volume limiting expansibilities Densities of the aqueous solutions of ionic liquid 1-butyl-3 metilmidazolium chloride [Bmim+][Cl-] were determined using a vibrating tube densitometer Anton Paar DMA 5000 at a temperature range between (283.15 - 218.15) K. The apparent molar volumes VVφφ of aqueous chloride1-butyl-3-methylimidazolium were calculated and adjusted to the Pitzer ion interaction model, obtaining the limiting apparent molar (0)VV (1)VV VV volumes VVφφ and Pitzer volumetric parameters ββ MMMM , ββ MMMM , CC MMMM at temperatures of 283.15, 288.15, 293.15, 298.15, 303.15, 313.15 and 318.15K, proving that this model adequately represents the experimental volumetric data below an ionic strength of 0.6018 mol / kg. Finally the limiting apparent molar expansibilities φφ 0 were calculated from the limiting apparent molar volumes at various temperatures and the results EE are discussed in terms of the interactions occurring in solution. 2014 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49631663016 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.186 Vol.81
